Yau's Affine Normal Descent: Algorithmic Framework and Convergence Analysis
Yi-Shuai Niu, Artan Sheshmani, Shing-Tung Yau
We propose Yau's Affine Normal Descent (YAND), a geometric framework for smooth unconstrained optimization in which search directions are defined by the equi-affine normal of level…

Affine Normal Directions via Log-Determinant Geometry: Scalable Computation under Sparse Polynomial Structure
Yi-Shuai Niu, Artan Sheshmani, Shing-Tung Yau
Affine normal directions provide intrinsic affine-invariant descent directions derived from the geometry of level sets. Their practical use, however, has long been hindered by the…
